Most electron heat transport is not anomalous; It is a paleoclassical process in toroidal plasmas

It is hypothesized that radial electron heat transport in magnetically confined toroidal plasmas results from paleoclassical Coulomb collision processes ( parallel electron heat conduction and magnetic field diffusion). In such plasmas the electron temperature is equilibrated along magnetic field lines a long length L (much greater than poloidal periodicity length piR(0)q), which is the minimum of the electron collision length and an effective field line length. Thus, diffusing field lines induce a radial electron heat diffusivity M equivalent to L/(piR(0)q) similar to 10 much greater than 1 times the magnetic field diffusivity eta/mu(0) similar or equal to v(e) (c/omega(p))(2).
